Abstract

The invention relates to a method for battery module balancing of a battery, which comprises at least one battery module string, wherein the at least one battery module string has a plurality of battery modules connected in series or parallel, wherein each battery module has a single or a plurality of battery cells connected in parallel or in series and a coupling unit which is designed to switch on and off the battery module, said method comprising the steps of: determining a battery module state of at least two battery modules; switching off individual battery modules having a low battery module state, wherein the low state is defined by a defined ratio to an initial state of the battery modules or by a result of a comparison of all detected battery module states. The invention further relates to a battery management system for carrying out said method and to a motor vehicle comprising such a battery management system.
